In an earlier post I queried the board about the possibility of a bad lifter (or two) causing a persistant miss at idle on up to 1700 RPM. This theory came about after adjusting the valves and finding that the effort to tighten the #1 intake rocker was significantly lighter than the rest. And after shutting the engine down, I checked the tightness of all the rockers by wiggling them by hand - the intake rocker on #1 was noticably "looser" as compared to the rest of the rockers, and the stud shows fewer threads than the other studs on the head. The stud is fine (not loose or pulling out), but the rocker tends to loosen very quickly after shutting the engine down - like the lifter bleeds out fast. Also, when the engine is running, the lifter dribbles oil rather than squirting like the lifters. I don't think this is a cam issue, but then again, I don't know much.
Two Questions:
Would it pose any problem to replace the lifters, rockers, pushrods and springs (has the original springs) while leaving the cam as-is? The engine has 52k original miles, so not sure how this might effect/upset the balance.
And finally - it there a chance that this is a problem with the distributor? It's the original 1111141 (and yes, it contains a new cap, rotor, condenser, wires, etc). Could a rebuild save removing the intake from the car? Or should I do both at the same time since it'd be apart?
Thanks in advance.
